In California, only people literally behind bars FOR A FELONY cannot vote.
I’ve you’ve finished your felony time, you can vote.
If you’re in jail for a misdemeanor, you can vote.
If you haven’t registered, you can vote.
Any resident of California, ex-felon or not, can show up to a polling place, complete the same-day registration process, and cast a ballot. They call it a “provisional ballot,” but that just means they count it last. But it’s a ballot like everyone else’s, and it get’s counted.
If you’re an ex-felon or think there’s any other reason you can’t vote, just look it up. You can vote just like everybody else. Duh, you’re a citizen just like everybody else and you paid your debt to society.
